Application filed January 8, 1916. Serial No. 71,012.

To all whom it may concern Be it known that we, SvnN SWANSON, a subject of the King of Sweden, and SIGURD N. Homrrs, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Fastening Devices, of which the following is a specification.

The present invention appertains to fastening devices for rails and consists primarily in the combination with a chair having a rail engaging element at one side and a relatively movable element at the other side for clamping the rail disposed between said elements, of means coacting with the last mentioned element to actuate the same to'cause clamping action and at the same time secure this rail engaging element from displacement by cooperation with the chair and the tie upon which the latter rests.

For a full understanding of the present invention, reference is to be had to the following description and the accompanying drawings, in which:

Figure 1 is a transverse sectional view through a device forming theembodiment of this invention. Fig. 2 is an enlarged perspective view of the fastening member for the movable clamping element. 3 is an enlarged perspective view showing the clamping element more clearly. Fig. i is a perspective view of one type of rail chair of which this invention consists. Fig. 5 is a perspective View showing the type of chair designed for coeperating with the main track and guard rails. Fig. 6 is a slightly different type of chair that may be employed within the scope of this invention. F 7 is a perspective view of the simplified form of chair.

Throughout the following detail description and on the several figures of the drawings, similar parts are referred to by like reference characters.

In premising the description of this invention it may be mentioned that the rail chair which forms the subject-matter thereof may be made in either of two ways, first by the process of casting where it takes the form shown in Figs. 1 and 4t, and second by the rolling and punching process where it assumes the form shown in one or another of the Figs. 5, 6 and 7. So far as the scope of the invention is concerned it is to be understood that the same is not to be confined to either one or the other of these constructrons inasmuch as it is merely a matter of consideration from the manufacturing standpoint and does not affect either the utility or the operation of the device.

Referring to Figs. 1 and i, it will be observed that the invention comprises a chair consisting of the plate 1 which is of sufiicient width. to receive the rail 2 thereupon and with which the upstanding rail engaging member 3 formed at one side of the chair en gages. This element 2 is preferably cast in this construction integral with the base plate 1 of the chair and fits snugly against the ball of the rail at the top portion thereof and against the base of the rail at the lower portion. Spaced from this member 3 the base plate 1 of the chair is formed with an aperture i in which is adapted to be received .the coacting rail engaging member 5 most clearly shown in Fig. 3. This member corresponds substantially in construction and form to the member 3 but is, of course, movable so as to obtain a proper clamping ac tion. The member 5, however, is provided with a longitudinal groove 6 adjacent to its base in which is received one side of the base of the rail. At the end of the movable clamping member 5 it is formed with a vertical groove or slot 7 merging into a head receiving seat 8 in its upper surface.

Another peculiarity of its construction is incidental to the inclination of the face 9 at the end of the member 5., the function of which will be more clearly set forth hereinafter. Upon seating the element 5 in the recess 4: it is designed to be actuated into clamping position by means of a specially formed fastening member clearly in Fig. 2 of the drawing. This member takes the form substantially of a spike having the lateral head or lip 10 and the shank 11. This shank, however, at its upper portion is provided with lateral wedgeshaped wings 12, the rear surfaces of which coincide with the surface of the shank 11. It will be observed also that intermediate this surface there is provided a plurality of serrations 13.

The fastening member described is designed to be inserted into place with the shank 11 nterlocked in the groove 7 of shown most the clamping member 5 and upon driving said member downwardly into the rail tie 14 on which the chair is seated the lateral wings 12 coact with the inclined end face 9 of said member 5 and the rear edge of the aperture l in the chair base causing the clamping member to move laterally into clamping engagement with the rail. I/V hen the spik member has been driven home its lip or head 10 will be received in the seat 8 and the clamping member thereby held against displacement. The serrations 13 on the rear face of the spike coact with the edge of the aperture 4 and the tie to prevent likelihood of the spike working out of its position.

In F 7 is a shown a simplified form of chair which is constructed by rolling the sheet of metal in a well known manner and upsetting from its body the upstanding rail engaging member 3 which coacts with the rail as clearly described in respect to the element 3 mentioned in the previous description. The base plate is formed also with transverse rib 1 in the rolling process and is designed to strengthen the base plate where the strain is greatest.

In Fig. 5 this same form of construction is further carried out in that the base plate is provided with a pair of upstanding members 3 to engage the main track rail seated upon said base plate. At a suiiicient distance from these members 3 the aperture 4t is provided to enable the disposition of a guard rail 2 atone side of the main track rail, the chair thus forming a common fastening means for the two rails.

In Fig. 6 is disclosed a slightly modified construction though still carrying out the same idea. In this form the base plate is punched out to form opposite rail engaging members 3, between which the meeting ends of two rails are adapted to be received. Opposite these arms, the openings l are provided so as to enable the positioning of the movable clamping members 5 in proper place for cooperation with the rail at the opposite side of the integral elements 3.

This type thus enables the joining of two rails together.

Having thus described the invention, What is claimed as new is:

1. In combination, a rail chair having an upstanding member coacting with the rail at one side and apertured at the other side of the rail, a clamping member disposed in the aperture for engaging the rail at the side opposite the upstanding member said clamping member having an end wall formed with a spike receiving groove, and a spike having a shank seated in the groove and provided with wedge means engaging the end wall at one side and a wall of the aperture at the other side.

2. A rail chair comprising a body of sheet material having a rail engaging member struck up from the body to coact with the rail at one side, said chair being formed with an aperture spaced from the engaging member, a movable rail engaging member disposed in said aperture to engage the rail at the opposite side, said movable member having an inclined end wall formed with a spike receiving grooveterminating in a head receiving seat, and a spike adapted to be interposed between the movable member and a wall of the aperture with its shank in the groove and head in the seat aforesaid whereby to wedge the movable member into clamping position.

8. In combination, a rail chair having a rail engaging member at one side thereof, a movable clamping member arranged at the other side thereof, and means for actuating said clamping member and anchoring it in position, said means comprising a fastening member having its shank interlocked with the clamping member, said fastening member being formed with lateral wings of wedge shaped construction adapted to coact with the end of the clamping member for actuating the same as aforesaid.

In testimony whereof we affix our signatures.
